SKEE-STIRRUR Specification of Letters Patent.

Patented June 23, 1908 i Application led March 9, 1908. Serial No.'420,016.

To all whom 'it may concern:

Be it known that I, CARL NORDLANDER, asubject of the King .of Sweden,residing at Norway, in the county of Dickinson and State of Michigan,have invented certain new and useful Improvements in Skee-Stirrups; Yand I do declare the following to be a full,-

' clear, and exact description of the invention,

such as will enable others skilled in the-art to which it appertains tomake and use the same. This invention relates to skee stirrups andespecially to that class of devices shown in my Patent No. 870,741, ofNov. 12th, 1907.

The object of the present invention is to provide a device of thischaracter which will prevent serious results from accidental falls, itbeing the articular object to release the user of the s ee. A furtherobject of the invention is the provision of novel means for holding theankle strap, to the heel yplate so as to allow disengagement thereofupon undue strain being exerted thereon, and means to accentuate theaction when the foot of the user assumes such a position with relationto the runner that a fall is unavoidable.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts',as will be more fully described and partlcularly pointed out in theappended dirimir dr E n t e accom anying awings i e 1 is a perspectiveviiiw; Fig. 2 alo 'tudlarl section; Fig. 8 a top plan view part y insection; A

Fig. 4 is a fragmentary diagonal section taken on the line 4-4 ofFig. 1. i

Referring more especially to the drawings, 1 represents the skee runnerupon the top of which adjacent its center is secured in any suitablemanner Vthe stirrup plate 2. At the forward end of the stirrup plate Isecure by rivets or otherwise thetoe plate 3 ha the toe strap 4 securedthereto by an a 'ary plate 5j arranged beneath the toe plate and avingpivoted thereto the rearwardly -extending shank plate 6. This plateextends rearwardly for some distance from thetoe plate and is providedwith a spring arm 7 the hee plate to a point adjacent the counter plate12 so that the heel plate and its associated Icounter may have sideadjustment. with respect to the distance to or from the J toe plate andits associated toe strap. This is done in order to adapt the device fordiierent sized shoes. Secured to the left hand ear 13 of the'plate 12 isthe strap buckle 14 which holds the ankle stra 15 1n adjusted position.The opposite en of the strap has secured thereto a pair of plates 16 and17 ex- 65 some distance beyond the strap paralle to each other so as t0overlie the ten right ear 18 of the counter plate.y The lower or. lnncrplate is perfectly plane throughout its length but the upper plate 17has stamped 70 up out of its body a curvilinear arm which forms a camsurface ada ted to be engaged by a conical stud 20 carried upon the ear18.

:A stud clamping member 21 surrounds the l plates 16 and 17 and isadapted to slide there- 75 oversto increase their pressure upon the ear18 and make the disengagement of the up er plate 17 with the conical lugmore or ess dilicult as the case may require.

This device hassuihcient holdupon the counter plate t0 prevent anydisengagement, except where extreme conditions occur and strains beyondthe normal are brought to bear upon the strap.

. It will be seen that when the heel of the wearer is held upon the heelplate by the strap 15 that the shank late will be held in adjustableengagement t erewith by reason of thev heel engaging the spring arm andholding its contact stud in engagement with the a ertures 10 of the heelplate. The heel `prate being free of the mounting plate 2 is ce to movewith the shank late as it pivots u (in its hinge connection with theauxiliary p a e 5. Y

When the operator or user of the, skee after a jump or a fall has thetoe of the skee runner engage the ground rior to the rest of the runner,the heel of t e wearer leaves the runner and rises with the shank lateon its I pivot. At this time it is almost impossible to avoid a fall anddisengagement of the foot from the stirru is absolutely necessary. lnorder to provi e for such accidents, I extend the heel of the toe plate3 a suitable distance 105 beyond the hinge connection oii the shank latewith the auxiliary plate so that it overies the same in position toengage an upstanding stud 22 which stops the upward movement of theshank plate and thereby quiring a more extendedexplanation.

throws additional strain u on the strap. This additional strain is sucient to disengage the plates from the ear 18 of the counter and thusreleasing the operators foot therefrom. The foot readily sli s out ofthe toe strap when thus disengage and the user is free to take anymovement he may see fit in respect to the position of the runners.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionWill be readily understood Without re- Varlous changes in the orm,proportion and the minor details of construction may be resorted toWithout departing from the principle or sacricin any of the advantage.of the invention, as eined in the appen claims.

I claim as my invention:-. 1. In a skee stirrup a toe plate and a heelplate, bmeans to secure the foot to the toe plate, means disengageablefrom the heel plate upon an excess strainfor securing the heel to saidheel plate and means to adjust said heel isecuring means.

2. In a skee stlrrup, a toe plate and a heel plate, a toe stra forsecuring the foot to the toe plate, 'a`hee plate and a pivoted shankplate adjustably connected to the heel plate.

3. In a skee stirrup, a front Iplate, means for securing the foot of thewearer thereto, an auxiliary plate secured to the other side of the toeplate, a heel plate, means for securing the Wearers foot to the heelplate said means being disengageable from the heel plate upon an excessstrain being applied thereto, and means carried by the shank plate andacting in conjunction with the toe plate to accentuate the strain Whensaid conditions ap ly.
